Abstract

Currently, there remains a paucity of comprehensive evidence concerning the concurrent presence of insomnia and anxiety in pregnant women. This study, employing convenience sampling, enrolled 1049 Chinese pregnant women. Key assessment instruments comprised a three-item Insomnia Symptoms scale, a two-item Generalized Anxiety Disorder Scale, as well as measures of demographic and pregnancy-specific characteristics. The findings revealed that the prevalence of insomnia and anxiety symptoms among the participants was 54.5% and 18.8%, respectively. Considering the heterogeneous patterns of co-occurring insomnia and anxiety, 30% pregnant women experienced high insomnia with moderate anxiety, while 70% pregnant women experienced mild insomnia with mild anxiety. This study found that educational level, trimester, miscarriage history, pregnancy complications and pregnancy-related anemia significantly affected co-occurring insomnia and anxiety in pregnant women. This study provides clinical advice for reducing sleep disorders and anxiety in pregnant women.
